Answer the questions(根据短文内容回答下列问题)Nowadays there is less and less contact (联络) between the old and the young. There are mainly four reasons for this, including the breakdown of the big family, working parents with little time to take care of their children, families that have moved away, and smaller flat with no room forgrandparents. But the result are the same–increasing numbers of children without grandparents and old people who have no contact with children,more old people who are lonely and feel useless, and more and morefamilies with young children who need more love and care. Itproblem in many countries.Now intergenerational(代际交流)programmes, designed to bring theold and the young together, are growing popular all over the world. Thereare successful examples of such programmes. There are schemes(方案)which involve older people visiting families who are having problems, maybelooking after the children for a while to give the tired mother a break. Or“ adopt a grandparent”in whichschemeschildren write letters or visit alonely old person in there area. One successful scheme in London pairs(使结对) young volunteer with old people who are losing their sight. The youngpeople help with practical things such as reading newspapers, reading bankstatements and helping with shopping, and the older people can pass ontheir knowledge and experience to their young visitor. For example, aretired judge may be paired with a teenager who wants to study law.If older people can understand and accept the youth of today, and sodo the youth, there will be less conflict(矛盾)in the world.102.

故选D。
2.在AlCl3溶液中逐滴加入NaOH溶液至过量,发生如下反应:3NaOH+AlCl3=Al(OH)3↓+3NaCl, A l(OH)3+NaOH=NaAlO2+2H2O。
已知NaAlO2易溶于水,则下列图像不正确的是( )A.B.C.D.【答案】A【解析】【分析】【详解】A、图中所示,随着氢氧化钠溶液的滴加,溶液中水的质量逐渐增大,当加入一定量时会出现滴加氢氧化钠溶液,而水的质量不增加的阶段而后继续增加;而反应的事实却是溶液中水会随着氢氧化钠溶液的滴加而不断增加,选项A错误;B、图中所示,随着氢氧化钠的滴加,溶液中的氯化铝不断形成氢氧化铝沉淀,沉淀质量逐渐增加。
至完全反应后,随着氢氧化钠的滴加沉淀逐渐减少。
符合氯化铝先与氢氧化钠生成氢氧化铝沉淀,然后沉淀氢氧化铝又和滴加的氢氧化钠生成可溶的NaAlO2的反应事实,选项B正确;C、图中所示,溶液的pH逐渐变大,符合氯化铝先与氢氧化钠生成氢氧化铝沉淀,溶液渐呈中性,然后沉淀氢氧化铝又和滴加的氢氧化钠生成可溶的NaAlO2而使溶液逐渐呈碱性的反应事实,选项C正确;D、图中所示,随着氢氧化钠溶液的滴加,溶液中铝元素质量减少至完全消失,之后随着氢氧化钠溶液滴加溶液中铝元素质量又逐渐增加,符合氯化铝先与氢氧化钠生成氢氧化铝沉淀,然后沉淀氢氧化铝又和滴加的氢氧化钠生成可溶的NaAlO2的反应事实,选项D正确。

One day Shankar stood at the gate, Shankar was a hunchback(驼背的人)We laughed and said,” Move out of the way, Shankar! Miss Bailey is going to enter!” Miss Bailey drove in and we all rushed to offer ur hands to her. But Miss Bailey looked past us all. “Will you park it for me?” She asked. We looked back to see who it was and were surprised to see it was towards Shankar “I don’t think so, Miss Bailey!”stammered(结结巴巴地说)Shankar. “Why? “You lazy fellow!” Said Miss Bailey playfully. “You don’t want to help your teacher, do you?” “Of course I want to, Miss Bailey!” whispered Shankar. “But I might drop your cycle!” “If you drop it, you pick it up!” said the teacher with a smile.With that she gave her cycle to Shankar and didn’t look to see how he’d manage. Pretending she had confidence in his abilities Miss Bailey turned and walked to class.We watched Shankar as she held her bike. We held our breath as we though it was going to fall. Dinesh rushed to help. “Leave it!” Shankar said, and we all stopped. It seemed that his hump(驼背)disappeared as he drew himself up to his full height, and then with growing confidence, he pushed Miss Bailey’s cycle to the parki ng lot. The school bell rang, and we rushed to class. Shankar was the last to enter, but we were surprised; It was a different boy who walked in.Miss Bailey didn’t even looked at him as he walked to her and handed her the keys.

Shane petted(爱抚)the old dog for the last time. In a few minutes, Belker died . The little boy seemed to accept Belker’s death. We sat together for a while after Belker’s death, talking about why animal lives are shorter than human lives. Shane, who was listening quetly, said, “I know.”“People are born so that they can learn how to live a good life like loving everybody all the time and being nice, right?” Shane said, “Well, dogs already know how to do that, so they don’t have to stay as 92 as human beings.”So remember, if a dog was the teacher, you would learn things like:When loved ones come home, always run to meet them.Run, 93 , and play daily.Let people touch youOn hot days, drink lots of water and lie under a big tree.When you are happy, dance aroundNever pretend to be something you’re notWhen someone is having a bad day, be silent, sit close by and nuzzle(轻触)them.Love people and don’t remember the wrong things they do 94 you.88.

Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺,每空格限填一词,首字母已给)More and more Japanese teenagers read novels on mobile phones(手机), n 95 on the paper.The phone novels are usually written by first-time writers usually in their tens or twenties. Several novels have been turned into real books. Love Sky, a story a 96 a boy with cancer, has sold more than 1.3 billion books and has been made into a f 97 .Many of the phone novels are influenced by comic(漫画)books because comic books are very popular in Japan. So phone novels are heavy in dialogue and have r 98 short paragraphs. Large empty spaces between sentences are used to mean that the characters are thinking.A mobile phone novel website, Maho i-Land which started several years ago, now has six million members and amillion novels on the site.However, some t 99 writers are angry about phone novels. They c 100 that phone noels are short of scene(缺少情景)and character development.Koichiro Tomioka, a professor at Kanto Gakuin University, said it was a new w 101 for writers to become known.He said, “It’s interesting. The problem is: can this new type of writer keep on writing books as a professional writer?”E. Answer the questions(根据短文内容回答下列问题)Nowadays there is less and less contact(联络)between the old and the young. There are mainly four reasons for this, including the breakdown of the big family, working parents with little time to take care of their children, families that havemoved away, and smaller flat with no room for grandparents. But the result are the same – increasing numbers of children without grandparents and old people who have no contact with children, more old people who are lonely and feel useless, and more and more families with young children who need more love and care. It’s a big problem in many countries.Now intergenerational(代际交流)programmes, designed to bring the old and the young together, are growing popular all over the world. There are successful examples of such programmes. There are schemes(方案)which involve older people visiting families who are having problems, maybe looking after the children for a while to give the tired mother a break. Or “adopt a grandparent” schemes in which children write letters or visit a lonely old person in there area. One successful scheme in London pairs(使结对)young volunteer with old people who are losing their sight. The young people help with practical things such as reading newspapers, reading bank statements and helping with shopping, and the older people can pass on their knowledge and experience to their young visitor. For example, a retired judge may be paired with a teenager who wants to study law.If older people can understand and accept the youth of today, and so do the youth, there will be less conflict(矛盾)in the world.102. Is there more and more contact between the old and the young?.103 How many reasons are mentioned(提到)for this situation?.104. Many old people feel l onely and useless, don’t they?.105. What is designed to bring the old and the young together?.106. Where does the successful scheme pair young volunteers with old people who are losing their sight?.107. If you take part in the “adopt a grandparent” scheme, will you pass on your experience or visit a lonely old person?I will .\108. Why are intergenerational programmes growing popular all over the world?.IX. Writing(作文)109. Write a passage of at le ast 60 words on the topic “I need …”. (以“我需要…”为题写一篇不少于60个词的短文符号不占格。
